Sex-specific differences in winter distribution patterns of canvasbacks
Winter band recovery distributions of North American Canvasbacks (Aythya valisineria) suggested that males and females exhibit comparable degrees of fidelity to general wintering areas. Of birds banded during the winter, the proportion of males was found to be higher in northern than in southern areas. Winter band recovery distributions of birds banded in particular areas during the summer were

Inferences regarding survival and recovery rates of winter-banded canvasbacks
Banding and recovery data from 3 populations of winter-banded canvasbacks (Aythya valisineria) were analyzed and survival and recovery rates were estimated. Sex-specific differences in these rates were detected in some populations, and lower survival rates were exhibited by females. Some geographic variation in survival rates was evident, suggesting that canvasbacks should not be managed strictl

Consistency in habitat preference of forest bird species
The important management conclusion that follows from our results is that the habitat requirements of most forest bird species, although quite specific for each species, apply generally throughout their breeding ranges. Thus a habitat management program that proves beneficial in one part of the breeding range of a species has a high likelihood of success in an area hundreds of kilometers away.

Canine tooth wear in captive little brown bats
Upper canine teeth of little brown bats Myotis lucifugus lucifugus held in stainless steel wire mesh cages underwent severe wear which exceeded that observed previously in caged big brown bats, Eptesicus fuscus fuscus. This suggests a relationship between amount of wear and size of the caged bats with damage increasing as size decreases. Rapid wear of canine teeth by little brown bats resembled th

Organochlorine residues in eggs of loggerhead and green sea turtles nesting at Merritt Island, Florida--July and August, 1976
Eggs from nine clutches of loggerhead turtles (Caretta caretta) and two clutches of green turtles (Chelonia mydas) were collected as they were laid on Merritt Island, Florida. Eggs were incubated, frozen, and analyzed for organochlorines. Levels of DDE and PCB, the major contaminants, averaged less than 0.08 ppm in loggerhead eggs and were even lower in green turtle eggs. These concentrations are
